Larger Mirrors

I
never really was satisfied with the stock side mirrors. They are too
small and too close to the side of the vehicle, limiting rear
visibility. With my Caddy Shack
installed, visibility is at a premium. I tried using a slightly larger
aftermarket mirror but it didn't hold up very well. Then I found the
pictured mirror but needed a way to mount it.

As you can see in the image, I used a piece of galvanized sheet metal
bent to fit the door contour. Two screws attach the top to the factory
mirror mounting holes and then beneath the mirror base, I used two
threaded inserts (1/4"x20) into the door panel. The mirror bolts
go through the base, the sheet metal and into the threaded inserts.
Seems to make a very solid mount and the extra mirror size allows the
addition of convex mirrors to the outer corner of the passenger side
mirror further improving visibility.
